A hearing to determine if attorneys are ready for the murder trial of the adoptive parents of two California City brothers who prosecutors say were killed was postponed Friday until next week.

Trezell, 36, and Jacqueline West, 33, have pleaded not guilty to two second-degree murder charges, a single involuntary manslaughter charge, two felonies of willful cruelty to children, felony conspiracy and a misdemeanor of falsely reporting an emergency in the deaths of Orrin, 4, and Orson, 3, West.
